# HERO CLASSES (NFTs)

Each hero is an NFT with specific traits that impact their performance in battle. Choose from 4 powerful classes:

* 🧙‍♂️ Mage – Long-range magical attacks; high critical rate, low defense.
* 🛡 Tank – Heavy armor and high resistance; short-range, slow attacks.
* 🗡 Assassin – Fast and agile; high critical hits, low armor.
* ⚔️ Warrior – Balanced stats; medium-range combat and solid durability.

Heroes can be upgraded with Gems and Gear, increasing their value and power.
